Based on this tutorial, I do the following things :1. Create a HOME variable, pointed to C:\Users\Andre

2. In the HOME directory, I make a .sbclrc file, which content is :(require :asdf)(require :asdf-install)(pushnew 'asdf-install:sysdef-source-dir-search asdf:*system-definition-search-functions*)

This is what I get when I invoke sbcl
